Plotly 箱形图关闭异常值检测

Plotly box plot turn off outlier detection

在Plotly(Python)中,箱线图默认检测离群值,如果有它判定为离群值的,则胡须不延伸到离群值。但是,我知道 none 我的数据点应该被视为异常值。是否可以关闭箱形图中的异常值检测,并将整个数据集视为异常值?

顺便说一下,我仍然想在箱线图旁边显示所有点,所以我不想使用选项 boxpoints=False 强制箱线图包含所有点。

似乎目前唯一的方法是使用多个轨迹并将它们调整到相同的位置,如下图和片段所示。如果您想了解一些详细信息,请查看末尾的片段和图表。

在下面的代码片段中,我使用 go.Box(x=x0) 对具有相同数据但标记和线条设置不同的两条不同轨迹来实现此目的:

剧情:

代码:

# imports
import plotly
from plotly import tools
import pandas as pd
import numpy as np
import plotly.graph_objs as go

# setup
np.random.seed(123)

# data
y0 = np.random.randn(50)-1
x0 = y0
x0 = [0 for y in y0]

# include an outlier
y0[-1] = 4

# traces
trace0 = go.Box(x=x0,
                y=y0, boxpoints = False, pointpos = 0,
                marker = dict(color = 'rgb(66, 167, 244)'),
)

trace1 = go.Box(x=x0,
                y=y0, boxpoints = 'all', pointpos = 0,
                marker = dict(color = 'rgb(66, 66, 244)'),
                line = dict(color = 'rgba(0,0,0,0)'),
                fillcolor = 'rgba(0,0,0,0)'
)

data=[trace0, trace1]

# figure
fig = go.Figure(data)
fig.show()

有关默认行为的详细信息:

如果未指定 Boxpoints,则行将不包括离群值:

剧情:默认

代码:

# imports
import plotly
from plotly import tools
import pandas as pd
import numpy as np
import plotly.graph_objs as go

# setup
np.random.seed(123)

# data
y0 = np.random.randn(50)-1
y0[-1] = 4

# traces
trace0 = go.Box(y=y0, pointpos = 0,
                marker = dict(color = 'rgb(66, 167, 244)'),

)

# figure
fig = go.Figure(trace0)
fig.show()

使线条包含离群值的唯一方法是通过设置 boxpoints = False

删除所有框点

剧情:


代码:

# imports
import plotly
from plotly import tools
import pandas as pd
import numpy as np
import plotly.graph_objs as go

# setup
np.random.seed(123)

# data
y0 = np.random.randn(50)-1
y0[-1] = 4

# traces
trace0 = go.Box(y=y0, pointpos = 0,
                marker = dict(color = 'rgb(66, 167, 244)'),
                boxpoints = False
)

# figure
fig = go.Figure(trace0)
fig.show()

当然,这不是您的目标。

希望对您有所帮助。如果没有,请随时告诉我。
